soc/intel/baytrail: add _HRV to GPIO ACPI devices

For some reason, the Windows LPEA drivers won't attach without
 _HRV (hardware version) defined for the GPIO controllers.
Add it, using value taken from Intel baytrail/valleyview edk2
reference code.

TEST=boot Windows 10/11 on google/rambi, verify LPEA drivers load
properly.
